v I v 1 I CAN.

' Application as June 28,

My improvedcan has for its object an integral can having a body portionand a top portion joined by a conventional double seam and the bodyportion provided with a tearing strip for opening the can; and when soopened, by removing the tearing strip, the cover is initially in andremains in frictional contact with the body portion whereby I attain acan of economical construction adapted to retain its contents undervacuum or pressure indefinitely until opened. My cans will easily stack,thus facilitating packing and transportation, and the can is especiallyadapted to retain the contents pure by the closure of the frictionalcover after the can is opened and during the time that the contents arebeing used from time to time.

The can of my invention is particularly adapted to the packing,preservation, transportation and use of ground coffee and the like.

By referring to the accompanying drawings my invention will be madeclear.

Fig. 1 is a fragmentary cross section through a portion of the cover andbody of the can of my invention, in which the metal sections are showngreatly enlarged, to bet ter illustrate the features of my invention.

Fig. 2 is similar to Fig. 1, except that the cover is shown infrictional engagement with the can body after the scoring strip has beentorn away and the can opened.

Fig. 3Vis a side view of the complete can of Fig. 1 to a reduced scale.

Fig. 4 is a plan view of an alternate form of can cover adapted tofrictionally hold an opening key therein. 7

Fig. 5 is a cross section on theline VV of Fig. 4 before the key hasbeen removed therefrom.

. Fig. 6 is a fragmentary cross section through the tearing stripportion of the body of the can of Fig. 1 and on the line VIVI of Fig. 7.

Fig. 7 is a front view looking from'the inside of the can body at thetearing strip portion and showing the scorings to set off the tearingstrip.

Throughout the figures similar numerals refer to identical parts.

A can body is shown by the numeral 1 to whichsis sealed the bottom 2 asby the double seam 1926. Serial No. 118,923.

The can top is shown generally by the numeral 4, double seamed to thebody portion at 5 and flanged downward at 6 forming a cylindricalsurface to engage the can body frictionally.

The body is beaded with an outwardly projectlng head 7 which stiifensthe body of the canretaining it in proper shape and frictionallyengaging the cover after the tearing strip is removed therefrom.

At 8 is a scoring line in the metal of the body parallel with andadjacent to the head 7 and at 9 a similar parallel scoring in the bodyportion adjacent to the double seam 5.

These scoring lines set off the tearing strip 10. At 11 is a tongueextending from the tearing strip with which an opening key is adapted toengage to start and wind off the tearing strip 10 to open the can, inthe conventional manner.

I prefer to form the scoring line 8 slightly above the bead 7 to-providea frictional surface at 12 which is a portion of the body inner surfaceand which when the can is originally sealed engages with the flangedportion 6 of the cover 1 so that when the tearing strip 10 has beenremoved, the cover is still in frictional contact with the body portionbefore it is pulled outward, and may be depressed as shown in Fig. 2 andfrictionally engage also a cylindrical portion of the body inner surfacebeyond the bead as at 7.

This construction enables the can to be entirely filled and sealed andto be retained closed by the cover in frictional contact with thesurface at 12 even before any of the contents have been removed from thecan.

The body is rolled from a sheet of fiat tin plate and the ends joined bythe body seam at 13.

The top and bottom are double seamed thereto at 5 and 3 respectively,providing a closed and sealed can.

Between the main scoring lines 8 and 9 are the conventional herring bonescorings as 14, 15, to insure the tearing of the metal of the bodyportion being retained along the lines of the scorings 8 and 9.

It will be noticed that the said top is flanged inwardly forming an endclosure portion overlapping the tearing strip 10 and that after theremoval of the tearing strip the said end closure portion engages thebody overlapping the bead.

At 16 is a conventional key which when engaged with the tongue 11 andwound about the rim of the can tears the strip 10 from the body portionaround the entire periphery. This leaves the cover 1 with its dependingflanged portion 6 friotionally engaged witlr the inner surface of thecan body at 12 and the cover may then be lightly withdrawn therefrom bythe fingers engaging the edge or seam at 5 and overcoming the aforesaidfriction. 1

preferred the bottom, may be further fianged' as shown in Figs. 1 and 5,to provide aholding means for the key 16.

Such a combination between the flanged portion of the can and the openeror key is more fully set forth in co-pending application Ser. No.116,392, filed June 16, 1926, while the invention to which thisapplication is directed is an improvement on my co-pend-V ingapplication No. 109,502, fi ledjMay 17, 1926. r

I claim 1. A can comprising a cylindrical body formed from a singlemetallic sheet, a top double seamed to said body, parallel scorings insaid body setting off a tearing strip adj a cent said seam, areinforcing external bead of arcuate section struck up from the sheetand parallel with and adjacent said strip, said top flanged inwardly andadapted to telescopically and frictionally engage against the innersurface of the can body and overlapping said bead section when thetearing strip has been removed. v 2. A can as set forth 1n claim 1\VllGlGlIL the inwardly flanged portion of the top extends substantiallydown to said bea d'before the tearing strip vis removed.-

3. A can comprising a cyclindrical body formed from a single metallicsheet,a top double seamed to said body, parallel scorings in said bodysubstantially adj ace'nt said seam and adjacent a reinforcing beadrespectively setting off a tearing strip, a rein forcingbead of ar'cuatesection struck up from the said sheet eXternalto said body and entirelybelow said tearing strip, said top flanged inwardly and forming an endclosure portion overlapping entirely said tearing strip and adaptedafterthe removal of said tearing strip totelescopically and'frictionallyengage agalnst the inner surface of the can body below said bead;
